BOTTLE-CAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 697,672, dated April 15, 1902.

Application filed November 23, 1901- $erial No. 8&366. (N0 model.)

To (all 21/700712, it may concern:

Be it known'that I, WILBER HUNTER SCOTT, a citizen of the Dominion of Canada, residing in Ottawa, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Bottle Capping Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

The object of this invention is to provide an improved machine for applying caps to bottles or other similar vessels, and especially to render such machines more convenient and certain in operation, so that bottles can be more easily and rapidly capped than heretofore.

The invention will be more fully described hereinafter with reference to the accompanying drawings, in which the improvements are illustrated, and in which Figure l is a view in side elevation of the improved bottle-capping machine. Fig. 2 is a vertical central section on the plane indicatcd by the dotted line 2 2 of Fig. 3. Fig. 3 is a front elevation. Fig. 4: is a view, partly in elevation and partly in vertical section, on the plane indicated by the dotted line 4 4 of Fig; l, the feed-slide, with its operating links and levers, being removed. Fig. 5 is a detail view of the feed-slide. Fig. 6 is an under side view of the machine, the links being removed.

In the machine represented in the drawings, which is adapted to apply pasteboard caps to milk-bottles, the caps to be applied are supported one upon another in a receiver a, which may be provided with a telescoping section b. The receiver is supported upon a base 0, which is preferably curved upward, substantially as represented, so there shall be no interference with bottles in close proximity to the one which is being capped. Upon the under side of the base 0 is secured a conical or flaring flange d to engage the mouth of the bottle to be capped and to center the same with reference to the plunger-head e, which moves within a suitable casing f, supported upon the upper side of the base 0 and in close proximity to the receiver a. The plunger-head e is carried by a rod 9, having a suitable handle 7b, the plunger being lifted after operation by a spring 2' within the casing. A stop 76 is adjustably secured to the rod 9 by any suitable means, as by a pin Zengaging one of several holes m in the rod, for the purpose of limiting the movement of the plunger. The cap a, which closes the top of the casingf and retains the spring '5, may be threaded onto the casing and adjustable for the purpose of limiting the movement of the plunger.

Pivoted upon the receivera are bell-crank leversn, one arm of each of which is connected by a link 0 with the plupger-rod g, being preferably connected therewith adj ustably, as by a pin 0 engaging one of several holes g in the rod g, so that the throw of the bell-crank levers 'n can be adjusted with reference to the throw of the rod g and plunger. The other arm of each bell-crank lever 71 is connected by a link 19 with the feed-slide g, which is formed as a plate, having a shoulder r and a forwardly-projecting tongue 8. The slide q moves in ways 0', formed in the under side of the base 0.

The plunger-head c is flat on its under side and slightly smaller than the cap to be ap plied, moving in an enlarged portion of the casing f. Within such enlarged portion are secured two yielding fingers 25, preferably fiat springs, one at each side of the casing, on opposite sides of the path of the tongue 8, the latter being somewhat narrower than the space below the two yielding fingers when in their normal positions, so that the fingers are not disturbed by the movement of the slide.

In the operation of the machine when'it has been placed upon the mouth of the bottle, which is centered by the conical or flaring flange d, the plunger is moved down ward,forcing into the mouth of the bottle a cap which has been placed by a previous movement of the parts between the fingers t, which serve to hold such cap in proper position beneath the plunger, so that it shall be carried downward by the plunger in true position into the mouth of the bottle. During the downward movement of the plunger the slide q is moved by the links 0, levers n, and links 19 to the rear, so that the shoulder 'r stands in the rear of the lowermost cap of the pile within the receiver. WVhen the plunger is released and is moved upward by the spring 2', the shoulder moves forward, carrying with it, by reason of the shoulder r, the lowermost cap of the pile, such cap being supported by the tongue 3. This cap is carried forward between the yielding fingers t, by which it is grasped and held when the slide retires. The machine is then moved to the next bottle to. be capped and the operations above described are repeated,

' the cap in each instance being supported by the fingers t in true position to be driven into the mouth of the bottle by the plunger after the feed-slide g has been withdrawn.

The advantages of the improved machine in certainty, rapidity, and convenience of operation will be readily understood and appreciated without further description.

I claim as my invention- 1. In a bottle-capping machine, the combination of a base, a cap-receiver mounted upon said base, a plunger, a casing mounted upon said base to support the plunger, a feed-slide supported by said base and operatively connected with the plunger to transfer the lowermost cap in the receiver into position beneath the plunger and two flat, spring-fingers vertically disposed within said casing on opposite'sides of the path of the feed-slide to receive and yieldingly hold the cap transferred by the feed slide, substantially as shown and described.

2. In a bottle-capping machine, the combination of a base, a cap-receiver mounted upon said base, a plunger, a casing mounted upon said base and supporting the plunger, a feedslide supported by said base and operatively connected with the plunger to transfer the lowermost cap in the receiver into position beneath the plunger, said slide having a forwardly-projecting tongue to supportthe cap, and two flat,spring-fingers vertically disposed within the casing on opposite sides of the path of the feed-slide to receive and yieldingly hold the cap when the slide and tongue are withdrawn, substantially as shown and described.

This specification signed and witnessed this 20th day of November, A. D. 1901.
